Gotham City is a problem, don't you agree? But.. what if it moves to Indonesia?

Another night in crime city, the Bat-family is at the Wayne mansion when they receive a news from commissioner if the supervillains escape again from Arkham.. Including Joker. And then disappeared without a trace.

The Bat Family wasted no time and track the location. When they got there last location the supervillains were seen, it was a dirty and abandoned building, there was nothing there, just a broken looking portal.

In the blink of an eye, The Joker appeared and quickly pulled a lever that made the same portal glow in a very strong blue color.

Before they knew it, they were violently and quickly sucked into a portal and thrown into a place completely different from Gotham.
